To aZZ whom, it may concern:

Beit known that I, DWIGHT S. RICHARDSON,

residing at New York city, in the county of New York and State of New York, have in vented certain new and useful Improvements ase section K and cons in Sectional Boilers; and I do hereby declare the following to be a full, clear,

' t 18 obvious tha sai intermediate sections In an invention relates to improvemore especially of-that type adapted for heating pura high boiler-pressure is not The boiler anisd in Fig. 1 is an eight-sectionboilei ffi ve of the sections being omitted inbrderthat the construction and arrangement'o'fthe sections may be more clearly shown. a" Each of the intermediate sections, (*Jis formed with a waterleg C at the rear 'a dapted to rest on the base-section and collectively he rear 01' the fire-pot: The'up'per por- 7 tions of these intermediate sections extend for ward over the fire-pot and preferably tali'ia caring or rest on a front section may be a water-front of ordinary construcut is in every instance provided-with 75 two, h the stoking or. fuel doors D, the sections.

' front torear I The objects of the invention are a sectional boiler th ther objects of provide a boiler of ample capacity and heatingsurfaee, but comparatively narrow from front to rear of the fire-pot in order to facilitate stoking and removal of ashes and also to proand efleetivecleaning of the sections and flues. he accompanying drawings, Figure 1 is cilitating stoking and removal of ashes. f

e overhanging portions of the sections," as will be seen from Fig. 2, will drain into the Water-leg at therear, but are provided with a series of transverse openings 0 and interm 8 5 diate circulating-ducts 0, connecting the and bottom portions, and at the rear each sec tion i i portion of the clean-out doors broken away.

tube boiler, but with tween them and to pass transversely through the passages a, which latter thus constitute a portion'o the combustion-chamber, and inasmuch as the surface area of these portions of the sections is greatlyinexcess of the other portions the boiler will hav'e'a very large firesurface in proportion to the size of'the boiler and will have all of the advantages of. a droptages of perfect drainage and circulation The end sections B B are preferably formed similar'to the intermediate sections, save that they have no-overhang, and the bottom portions constitute the side vwalls of the fire-pot,

".able water-circulating openings c in the'sections at appropriate points, top and ,29- bottom, for the flow-of water and steam from Y The edges of the flue-openings (J are flanged, as at (i, so as to fit tightly together, and suitare formed section to section. I

The products of combustion pass up between the sections and off toward one end, as indicated by the arrows, Fig. 1, said productsreturnin g to the opposite end of the boiler through the smoke-flue formed by the openings-C ate stack, and the arrangement is preferably such that the. stack in the several sections and thence to 'or discharge-flue may be located at either end of the boiler, as found most convenient for any particular situation.

Various Ways of forming the communication between the combustion-chamber and smoke-flue at one end and between the smokeflue and stack at the opposite end of the furin the accompanying shown clearly in r is preferably provided with large clean-out doorsF, which will give free access both to the smoke-flue and tothe passages 0 from one end tothe other of the boiler. At the opposite end a smoke-box G is provided for conducting the products from'the smoke-flue C to the stack-opening g, a diaphragm or de- ,l,ector G being preferably provided in this box to deflect the products downwardly in passing thfi'o gh the box. The bottom of the box is rrovided with a clean-out door G and adirec. 'fdamper H. By opening the latter the prdducts may pass directly from the combus'tion-chamber and passages 0 through the box G to the stack instead ofv passing indirectly thereto, as before explained.

Obviously the smoke-boxes may be made the additional advan:

raises 1 to it either end of the furnace, and thus with a furnace'af the same constructionit may be set to have'either a' right or left hand discharge.

Having thus described my invention, what I claim as new,- and desire to secure by Letters Patent, is 1.. In a sectional boiler wherein the sections extend from front to rear, the combination of the end sections, the intermediate sections each having an overhanging ferwardly-extending portion between which the products of combustion pass and transverse openings in said overhanging portions for the passage of products toward the ends of the furnace, said sections also having registering openings forming a return smoke-flue, a duct for the passage of products from the combustion-chamber to one end of said flue and from the opposite end of said flue to the stack; substantially as described.

2. In a sectional boiler wherein the sections I front to rear, the combination-of the end sec tions, the intermediate sections each having-a down weirdly-extending water-leg at the back and an overhanging forwardly-extending portion with transverse passages therein, said a portion of their area to permit products to pass between the sections and having registering openings in rear of said overhanging portions to form a smoke-flue, a duct at. one end of the furnace to carry the products into the smoke-flue and a duct at the other end of the furnace to carry the products from the smoke-flue to the stack; substantially as described.

3. In aboiler, the combination with the end sections having transverse openings therein, of the intermediate sections having the relatively thin overhanging portions'located' in the combustion-chamber and having transverse openings therein for the passage of products toward the ends of the furnace, said sections having registering openings at the rear products to and from said smoke-flue; substantially as described.

4. In a boiler, the combination with the end the intermediate sections having ing water-legs and tions at rear top and front and central portions spaced. apart to permit products to pass between them, said central portions being provided with lSl'flIiV6I'S6 openings to permit the products to pass toward the ends of the fur nace, said sections also having registering openings forming a smoke-flue extending from end to end of the furnace, of smoke-boxes at the ends of the furnace, one forming a duct to carry the products into the smoke-flue, th

forming 'a return smoke-flue and smoke-boxes outs de of the end sections for conducting the are arranged side by side and extending'fromoverhanging portions being thin throughout sections having transverse openings therein,

the dependabutting peripheral por-' other forming a duct to carry the products to the stack and a direct-draft damper located in the latter and operating to close the transverse openings in the central port of the end section;

substantially as described.

sections extending from frentto rear and arranged side by side to form' a combustionchamber, the intermediate sections having overhanging portions projecting into the cornbustion-ehamber' with-transverse openings in said overhanging portions, the sections also having transverse registering openings in rear of the combustion-chamber forming a transverse smoke-fiue entirely within the sections, a duct at one end for carrying the products -from the combustion-chamber to the said smoke-flue and a snibke 'boxpnthe outside of the boiler at the opposite/end of said flue for conducting the produ' ts /r'om the flue to the stack; substantially as described.

7. In a boiler, the combination of a series of sections extending from front to rear and arranged side by side to form a combustionchamber, the intermediate sections having overhanging portions projecting into the com bustion-chamber with transverse openings in said overhanging portions, the sections also having transverse registering openings in rear of the combustion-chamber forming a transverse srnoke-fluc entirely Within the sections, a duct at one end for carrying the products from the combustionchamber to the said smoke-flue, a smol e-box at the opposite end of the furnace into which the flue opens, an

exit-o enin in said box and a direct dam J81 between the C0111lJUStlOIlwfillZlHllJGi and smokebox; substantially as described.

8. In a boiler, the combination of a series of sections arrangedside by side to form acom- I bustion -ehamber, the intermediate sections having relatively thin portions projecting into the combustion-chamber with transverse openings in said thin portions and registering transverse openings in the sections in rear of the thin portions to form an unbroken smoke-flue from side to side of the sections, of smokeboxes at each end of the boiler for conducting the products to and from the smoke-fiue and a clean-out door in line with the transverse o enin s in the sections substantiall I as de- 1: 9 5
